Mumbai: Actors John Abraham and Kangna Ranaut promoted their forthcoming film ‘Shootout at Wadala’, based on Mumbai’s first-ever registered police encounter.

Present at the event were the film’s director, Sanjay Gupta and its producer Ekta Kapoor and many actors.

Abraham, who plays the role of gangster Manya Surve, told reporters that the film depicts scores of encounters between the underworld mafia and the state police during the period when the goons dominated the city.

Excited about his role, Abraham described it as a lifetime opportunity for him and he was working on hard on it.

"I love this film and for me it is, on a very serious note, a career defining films something that I have taken very very seriously," said Abraham.

The film is a sequel to Gupta`s previous movie `Shootout at Lokhandwala`, which was based on the encounter at Lokhhandwala in 1992, when then police commissioner Aftaab Ahmed Khan shot Dawood Ibrahim``s aides, including Maya Dolas and Dilip Bua.

This caused massive controversy after it was rumoured that Dawood had sought the killing of his aides in an act of revenge.

Ranaut said promoting the film was an important medium to connect with the masses.

"Wherever we get a chance to promote our film, we reach there. There is nothing wrong in promoting the film. I think, one should not leave any stone unturned to promote the film and extensive promotion does not create any problem," said Ranaut.

Shootout at Wadala is slated for release on December 7.

Prominent Bollywood music directors Pritam, Vishal and Shekhar have composed the music for the film.

Sanjay Gupta has a long list of dark thrillers supporting his film career. Much of his work has been criticized as re-interpretation of other films, both Hollywood and other international pieces.
